Let's divide 305502 by 1
The aim is to understand the frequency of 1 in 305502.

Moving on to step 1:
1 goes into 3 3 times with a remainder of 0.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtracting 3 from 3 leaves us with 0.
Append the next digit (0) from the dividend to 0 and continue with: 0 / 1

Let's proceed to step 2:
1 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 30.0
The remainder is 0 after subtracting 0 from 0.
Grab the next digit (5) from the dividend, add it to 0, then carry on: 5 / 1

Moving on to step 3:
The number 1 fits into 5 5 times, leaving a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 305.0
If we subtract 5 from 5, we get 0.
Append the next digit (5) from the dividend to 0 and continue with: 5 / 1

Going ahead to step 4:
If we divide 5 by 1, we get 5 and a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 3055.0
If we subtract 5 from 5, we get 0.
Take the next digit (0) from the dividend and append it to 0, then repeat: 0 / 1

On to step 5:
1 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 30550.0
Deduct 0 from 0 and we're left with 0.
Take the next digit (2) from the dividend and append it to 0, then repeat: 2 / 1

Step 6:
If we divide 2 by 1, we get 2 and a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 305502.0
If we take 2 away from 2, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 7:
1 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 305502.0
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 8:
1 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 305502.0
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 305502.0, with a leftover of 0.0.
